If you floor it with the VDIM off will the tires spin from start? Just by hitting the gas paddle?
Yes. I just tried it again this morning. ECT control off, VDIM off. Hit the gas hard from a standstill. Car revved immediately, tires spun and car fishtailed left then right then got traction and next thing I knew I had caught up with traffic. No delay in power, now waiting, just goes.
